OK, let me start by saying that I know that lard comes from pigs, but I didn't have any pork fat, so I used what I had. Whenever I trim meat for dinner, I always save the fat and meat scraps. DH said we needed the room in the freezer for real food, so I decided to thaw it all out and put it thru a meat grinder. I had mostly beef scraps with some lamb. I put all that grisely, fatty goodness in an enamel lined cast iron pot, and set the heat on med. After it all melted I had maybe 8 cups of hot fat and tissue. I added 4 cups of water and brought the mixture briefly to a boil. I let it cool, and then put it on the back porch for the night (it wouldn't fit in the fridge). The next morning I had a nice thick disk of fat...sitting on a big block of gelatin! It was easy enough to remove the fat and re-melt it. I plan on repeating the process several times to "clean" all the meat out of the fat. But what should I do with the hamburger/gelatin stuff? I could heat it up and strain the meat out...but then what? Will wild birds eat it? Will chickens eat it? Has anyone else done this?
